HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 927, 680, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 927, 680, 969 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 927, 680, 969 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 927, 680, 969 is 1.
HCF(927, 680, 969) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 927, 680, 969 is 1.
Step 1: Since 927 > 680, we apply the division lemma to 927 and 680, to get
927 = 680 x 1 + 247
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 247 and 680, to get
680 = 247 x 2 + 186
Step 3: We consider the new divisor 247 and the new remainder 186, and apply the division lemma to get
247 = 186 x 1 + 61
We consider the new divisor 186 and the new remainder 61,and apply the division lemma to get
186 = 61 x 3 + 3
We consider the new divisor 61 and the new remainder 3,and apply the division lemma to get
61 = 3 x 20 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 927 and 680 is 1
Notice that 1 = HCF(3,1) = HCF(61,3) = HCF(186,61) = HCF(247,186) = HCF(680,247) = HCF(927,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 969 > 1, we apply the division lemma to 969 and 1, to get
969 = 1 x 969 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 969 is 1
Notice that 1 = HCF(969,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
